ODORLESS AND HUMIDITY-SUPPLYING GAS HEATING-STOVE.

Application filed March 3, 1917. Serial No. 152,180.

To all whom it may concern:

Be it known that L-BARRY Ivon, a citizen of the United States, residing at the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Odorless and HumiditySupplying Gas Heating-Stoves, of which the following is a specification,

The present invention appertains to that type of stoves or heating apparatus, in which the ordinary commercial gas employed for consumption in furnishing light or heat is used as fuel, and it consists in certain peculiarities of the construction, novel arrangement, combination and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed. 7 1 While the invention relates more particularly to heating stoves,in contradistinction to ranges and stoves employed for cooking purposes, and is so shown in the accompanying drawings and will be so referred to hereinafter, yet it will be understood that it is applicable for use in connection'with gas ranges and cookingstoves, and that numerous modifications and variations may be made the-rein without a departure from the spirit of the invention.

The main object of the invention is to provide simple and efficient means for the economical consumption of gas in connection with a stove, so as to furnish from the gas and stove, a maximum amount of heat, without the usual sensible dryness or lack of moisture, incident to the heat produced by gas-stoves of the type commonly heretofore in use, and without the emanation of the usual noxious, poisonous and disagreeable odors, soot and dust, or in other words, to provide a stove, which, by reason of the peculiar and novel construction and operation of its parts, Wlll prevent the deleterlous odors or fumes from the gas escaping into the room, and commingling with the air to be breathed, and will conserve the moisture in the air, or supply moisture thereto as it is heated. 1

In the accompanying drawings, which serve to illustrate an embodiment of the invention- Figure 1 is a plan View of the stove.

Specification of Letters Patent. Patented Ni 13 191 7 I The body or frame of the stove, 1s designated by the reference numeral 10, and the same may be of any suitable size, and shape, but preferably rectangular as shown, with open places 11 in its sides and ends for the free admission of air to the burner and around the same. The frame or body 10 is provided with a leg or upright 12 at each of its corners, which are braced. by a horizontally disposed connecting member or floor 13, which is located at a suitable distance from the lower ends of the legs 12, and serves as a support fora housing 14 for the burner 15, which may be of the ordinary or any well known construction and is supported within the housing 14: in any desired manner. Communicating at one of its ends with the burner 15 is a supply pipe 16 for the gas, which pipe extends horizontally from the housing let to near one end of the frame and from thence upwardly through the top of the frame near one of the corners thereof as will be readily understood by reference to Figs. 1, 2 and 3- of the draw ings. On the upper end of the supplvpipe 16 is mounted a valve casing 17 see F1g. 5, which is provided with a valve chamber "or cavity 18 in its upper portion, the upper end of which cavity is closed-by a screw loo plug, which is provided centrally with an 3 opening 20 having a valve seat21 in its lower end- The plug 19 also has horizontally located therein an opening;22 which communicates with the opening 20 and also with an opening 23 in the wall of the casing roe 17 near its upper end. Loosely mounted in the opening 20 is a valve stem 24- which has on its lower end a valve 25 provided with a pointed end 2 adapted to fit. a a

27 in the upper portion of an opening 28 in the casing 17, which opening communicates with the supply pipe 16, as is clearly shown in Fig. 5 of the drawings. The upper end of the valve is tapered as at 29 to fit the seat 21 in the lower end of the opening 20 of the screw-plug. The valve stem 2 1 is provided above the valve 25 with a plurality of annular grooves 30 which are located near the inner end of the opening 22 and are for engagement with the tapered end of a bolt 31 which is loosely mounted in the opening 22 and is actuated by a spring 33 which rests at one of its ends against the bolt 31 and at its other end against an adjusting screw 34 which is located in the opening 23 and by turning which in the proper direction, it is evident that the tenion of the spring 33 may be regulated as desired. the valve stem 2% is screw-threaded and has adjustably mounted thereon a valve 35 which is adapted to be seated in a seat 36, located in the upper end ofthe opening 20 of the screw-plug. Adjustably mounted on the upper end of the valve stem 24: is a nut or head 37 between which and the top of the plug 19 is located a spiral spring 38 which rests at one of its ends on said plug and at its other end against said head. Leading from the cavity or valve chamber 18 is an opening 39, which communicates with an opening 40 in a nipple 41, to which a tube or rubber hose, an, leading from a supply of gas, not shown, may be attached at one of its ends. The nipple all is provided with a shut-off valve 12 for the control of the flow of gas therethrough, and maybe secured to the valve casing 17 in any suitable way. 7

Located vertically in the lower portion of the valve casing 17 is a small opening 13, which has a valve seat 11 at its upper end for a needle valve 45, adjustably mounted in the screw -alug 19, which valve is used for regulating the flow of gas through the channel 13 to a pilot pipe 46, whichleads to the burner15', as is clearly shown in Figs. 2 and 3 of theldrawing's.

Extended through a suitable opening in the top of the ho'usingla for the burner, is a neck 17 of a hood %8, which is downwardly flared as shown, and located mainly within the housing 1 1 andjust above the burner 15. This hood is by preference provided with a perforated downwardly convexed member 49 located just above the burner 15 for the purpose of acting as a mixer for the air and gas as the latter issues from the burner. The upper end of the neck 17 is secured to a collar 50 mounted in a suitable opening in the bottom of the radiating chamber 51, which is by preference, box-like in shape and mounted centrally on the top As shown, the upper portion of,

52 of the stove, yet so that a portion of said chamber Will extend a suitable distance below said top, as is clearly shown in Figs. 3

and 7 of the drawings. Each end of the chamber casing 51 is provided with an opening 53, around each of which is seci'lred to the outer surface of the end of the casing 51 a pipe'or conduit 54, which pipes are slightly d flected toward one side of the frame of the stove and then projected downwardly so that their lower ends will enter suitable openings in the tops of the tanks 55, one of 3 51 of the stove. As will be clearly seen by reference to Figs. 1, 4 and 6 of the drawings the tanks 55 as well as the boxes 56 in said tanks, are located transversely with respect to the stove frame or body, and that the boxes 56 are considerably shorter than the tanks 55, thus leaving a space between one of the ends of each of said boxes and one of the ends of each of said tanks, which spaces or compartments are closed by removable covers 57, which rest on the top 52 of the stove and close suitable openings therein, which openings afford access to the tanks 55, so that by removing the covers 57, water may be supplied to the tanks. As the boxes 56 are without bottoms, it is'apparent that the water will rise therein to a level with the water contained in the tank, in which said box is located. Transversely journaled in the upper portion of each of the boxes 56 is a shaft 58 which is located near the conduit 551-, which communicates with said box.

Mounted at one of its ends on each of the shafts 58 is a swinging member 59 which has at each of its edges a depending side piece 60 which side pieces are substantially co-extensive with the member 59 or board, which member has near its free end an opening, diametrically across which is extended a bar 62havingan opening 63' in its middle for the reception and operation ofa valve stem 64 which projects upwardly from a float valve 65, which valve is for the purpose to be presently explained. Surrounding. the opening in the board or member 59, and secured to the lower surface of thelatter, is a circular or ringlike piece 66 of any suitable porous material, such as tripolized" stone, which is provided with spaced apart teeth 67 which extend into the water within the tanks 55 and boxes 56 and will absorb he same or will draw the same upwardly by capillary attraction. As the teeth are spaced apart they will afford passageways 61 for the heated'air as it passes through the conduits 54 into the boxes'56, so that it may escape through the passage-ways 61 in the members 59 and from thence out into the room through the upright tubes 68, one of which is mounted on the top of each tank 55 near it-s end opposite the removable cover 57 thereon. The tubes 68 are located directly over the openings 61 in the members 59, and each of said tubes is provided with a pair of slots 69 arranged vertically in the tube and diametrically opposite each other to afford guide-ways for a cross-bar 7 O, which is mounted on the upper end of each of the valve stems 64, which stems project into the tube 68, as is clearly shown in Figs. 6 and 7 of the drawings. served by reference to Figs. 1 and 2 of the drawings, one of the bars 70 is extended at one of its ends, through one of the slots 69 in one of the tubes 68, and projects over the head 37 on the valve stem of the gas controlling valve, which, as before stated, is mounted on one end of the stove frame, near one of the corners thereof. Leading from the bottom or lower portions of the tanks 55, is a drain pipe 71 which extends through one end of the stove frame and is provided with a valve 7 2, which may be opened when it is desired to drain the tanks 55 of their contents. Extended transversely with respect to the chamber 51 and within the same, are a pairof deflecting plates or partitions 73, which extend from one side of the chamber 51 to the other side and are secured at their upper edges to the inner surface of the ends of the chamber-casing 51, just above the openings 53 in said ends. As shown in Fig. 3 of the drawing, these plates or partitions 73 converge toward their lower edges and are supported at said edges by means of a bracket 74, which is extended transversely with respect to the bottom of the casing 51 and diametrically across the collar 50, which depends from said casing.

From the foregoing and by reference to the drawings it will be readily understood and clearly seen, that by turning the valve 42 on the nipple 41 of the gas controlling valve casing 17 gas will be supplied to the chamber 18, and when the parts are in the positions shown in Figs. 1 to 5 inclusive of the drawings, the gas will pass through the channels 28 and 43 and from thence through the supply pipes 16 and 46 respectively, to the burner 15 and that, as it is discharged from the burner it may be ignited, thus heating air entering the housing 14' for the burner, which heated air-will pass through the hood 48, neck 47 and collar 50 into the radiating chamber 51, where it will be As will be obdivided into two currents or volumes, which will pass out through the openings 53, into the conduits 54 and from thence into the boxes 56 of the tanks 55, from which places it will pass between the teeth 67 of the porous rings or members 66, which are continuously held in contact with the water in the boxes and tanks by reason of the pivotal movement of the members 59, which carry the porous or absorbent members. In this operation the heated air will come in contact with the upper surface of the water in the said vessels, and will also be subjected to the moisture carried by the teeth 67 of the porous or absorbent members, after which it will pass out through the tubes 68 into the room inipractically a pure condition and without deleterious odors, yet carrying humidity about equal to that of the atmosphere. As the water in the tanks evaporate, it is obvious that the float valves 65 will descend with the volume of water and that in so doing, the free portions of the members 59 will also descend, but that the sides 60 of said members will always be submerged so as to provide achannel above the surface of the water for the passage of the heated air through the openings 61 in the movable members 59; It is also apparent that, as the float valves 65 are lowered by the evaporation or lowering of the water level the bar 7 0 on one of the valve stems 64 will strike the head 37 on the stem 24 of the gas control valve 25 and depress said head and valve,-until the latter is seated in its seat 27, when it is obvious the supply of gas to the burner will be shut off, except through the pilot tube 46, and that the operation of the stove, without. water in the tanks there- 1 of, will be automatically prevented. As the valve stem 24 of the gascontrol valve 25 is depressed from its position shown in Fig. 5, so that the valve 25 will close'the seat 27, it is evident that the spring pressed bolt 31 will be shifted from the lower groove 30 to the upper one in said stem and thus hold the valve in such position as to prevent gas passing through the channel 20 or through the channel 28. If it is desired to regulatethe supply of gas through the channel 43 and pilot tube 46, it is only necessary to turn the needle valve 45 in the proper direction, as is obvious. In order to retard the progress of the heated air and products of combustion as they arise from the burner, each of the deflecting plates or partitions 73 is provided on its lower surface with a number of spaced apart bafiie plates 74, which are located transversely with respect to the plates" or partitions73, as is clearly shown in Fig. 3 of the drawings.

Vhile my inventlon 1s primarily intended for use with gas as fuel, yet it is-apparent that any easily vaporizable hydro-"carbon psi oils, such as kerosene or gasolene, may be employed instead of gas, by simply supplying the apparatus with a suitable burner for such oils, without departing from the spirit of the invention.
